IMPROVEMENT IN COOKING-VESSELS Specification forming part of LettersPatent N 0. 175,710, dated April 4,1876; application filed February 5,1876.

4 State of New York, have invented a new and useful Improvement inDouble-Bottom Cooking-Vessel, of which the following is a specification.

The figure is a vertical section of a cookingvessel illustrating myinvention.

The object of this invent-ion is to furnish improved cooking-vessels,which shall be so constructed that the article to be cooked will beprotected from burning, however hot the fire may be, which will enablethe contents of said vessel to be raised to any desired temperature, andwhich shall be simple in construction and inexpensive in manufacture.

The invention consists in a double-bottom cooking-vessel in which thesecond bottom has an inwardlyinclined flange formed upon it to fit uponthe sides of the main vessel, where it is secured in place by a beadformed u on the outer surface of said sides and be inward, or is madenarrower at its mouth than at its base. The flanged bottom B is made ofsuch a size as to fit upon the lower part of the sides of the vessel A.A bead, a, is then formed around the lower part of the sides of thevessel A, beneath the edge of the flange b, by spinning or pressing agroove around the inner surface of said sides, as shown in the figure.This construction secures the second bottom to the vessel A in aconvenient and inexpensive manner, Without brazing or riveting, andforms an air-chamber in the bot tom of the vessel, which protects thecontents of the vessel from being burned, however hot the fire may be,and at the sametime allows the said contents to be heated to any desiredtemperature.

Having thus described my invention, I claim as new and desire to secureby Letters Patent The combination of body A and bottom B,

secured together by the bead a on the former and the flange I) on thelatter, as shown and described, whereby only that portion of the vesselis made double which comes in contact with the fire.
